I've made numerous auction purchases from both Ebay and Amazon, as well as Yahoo!. I've been pleased with the merchandise and the merchants I've encountered. Each of these sites rates the Seller, letting you read the feedback from other Buyers about the Seller. Good information to review prior to bidding! These sites also have very good search functions.
